The X-ray bursts of XTE J1739-285: a NICER sample
Peter Bult, Diego Altamirano, Zaven Arzoumanian +10
In this work we report on observations with the Neutron Star Interior Composition Explorer of the known neutron star X-ray transient XTE J1739-285. We observed the source in 2020 F…
Discovery of Thermonuclear Type-I X-ray Bursts from the X-ray binary MAXI J1807+132
A. C. Albayati, D. Altamirano, G. K. Jaisawal +13
MAXI J1807+132 is a low-mass X-ray binary (LMXB) first detected in outburst in 2017. Observations during the 2017 outburst did not allow for an unambiguous identification of the na…
Discovery of thermonuclear (Type I) X-ray bursts in the X-ray binary Swift J1858.6-0814 observed with NICER and NuSTAR
D. J. K. Buisson, D. Altamirano, P. Bult +22
Swift J1858.6-0814 is a recently discovered X-ray binary notable for extremely strong variability (by factors in soft X-rays) in its discovery state. We present the detectio…
The NICER View of the 2020 Burst Storm and Persistent Emission of SGR 1935+2154
George Younes, Tolga Guver, Chryssa Kouveliotou +12
We report on NICER observations of the Magnetar SGR~1935+2154, covering its 2020 burst storm and long-term persistent emission evolution up to days post outburst. During t…
NICER Observation of the Temporal and Spectral Evolution of Swift J1818.0-1607: a Missing Link between Magnetars and Rotation Powered Pulsars
Chin-Ping Hu, Beste Begicarslan, Tolga Guver +13
We report on the hard X-ray burst and the first ~100 days NICER monitoring of the soft X-ray temporal and spectral evolution of the newly-discovered magnetar Swift J1818.0-1607. Th…
Proper motion, spectra, and timing of PSR J1813-1749 using Chandra and NICER
Wynn C. G. Ho, Sebastien Guillot, P. M. Saz Parkinson +7
PSR J1813-1749 is one of the most energetic rotation-powered pulsars known, producing a pulsar wind nebula (PWN) and gamma-ray and TeV emission, but whose spin period is only measu…
